I made up the I/7b list a few years ago for a campaign set, then upgraded it to DBA3 standards soon after the purple book was released. I have used then at tournaments - both in 2.2 and 3 conditions.
When they last took the field under DBA3 it was with three of the Ps subbed out and replaced by Sea Peoples allies (1xHCh, 2x3Bd) and they won 5 games from 6. A similar performance on day 2 with the Konstantinian Byzantine gave me the overall win at Cancon 2019.
More recently I painted up I/17a - once again for a campaign set - completing them earlier this year. There should be pictures up of them in the DeBellis Antiquitatis Group on the Book of Face - around March 20th this year I think.
Because it has my troops all over it. THAT makes it MINE!!!!
